Unpack bit-fields from a 64-bit value

Extracts multiple values from a packed 64-bit value according to specified bit widths.

Usage

ffi_unpack_bits64(packed_value, widths)

Arguments

packed_value

Packed value (as double for 64-bit range)

widths

Integer vector of bit widths for each field

Value

Integer vector of unpacked values

Examples

packed <- ffi_pack_bits64(c(1L, 5L, 12L), c(1L, 3L, 4L))
ffi_unpack_bits64(packed, c(1L, 3L, 4L)) # c(1, 5, 12)
#> [1]  1  5 12
